* Advisory ID: DRUPAL-SA-CONTRIB-2009-016 * Project: Wikitools (third-party module) * Version: 5.x, 6.x * Date: 2009-March-25 * Security risk: Less critical * Exploitable from: Remote * Vulnerability: Cross-site scripting -------- DESCRIPTION --------------------------------------------------------- The Wikitools module provides several options to get a more wiki-like behavior for Drupal. On several pages, the Wikitools module prints out a parameter without escaping it. Malicious users are thus able to execute a cross site scripting [1] (XSS) attack when they entice users to visit a specifically crafted URL. This may lead to a malicious user gaining full administrative access. -------- VERSIONS AFFECTED --------------------------------------------------- * Wikitools 5.x-1.x prior to 5.x-1.3 * Wikitools 6.x-1.x prior to 6.x-1.1 Drupal core is not affected. If you do not use the contributed Wikitools module, there is nothing you need to do. -------- SOLUTION ------------------------------------------------------------ Install the latest version: * If you use Wikitools 5.x-1.x upgrade to Wikitools 5.x-1.3 [2] * If you use Wikitools 6.x-1.x upgrade to Wikitools 6.x-1.1 [3] See also the Wikitools project page [4]. -------- REPORTED BY --------------------------------------------------------- Charlie Gordon [5] of the Drupal Security Team [6]. -------- FIXED BY ------------------------------------------------------------ Charlie Gordon [7] of the Drupal Security Team [8]. -------- CONTACT ------------------------------------------------------------- The security contact for Drupal can be reached at security at drupal.org or via the form at http://drupal.org/contact.
